Intestinal metabolism of sulfur amino acids [PDF]
Nutrition Research Reviews, 2009 The gastrointestinal tract (GIT) is a metabolically significant site of sulfur amino acid (SAA) metabolism in the body and metabolises about 20 % of the dietary methionine intake which is mainly transmethylated to homocysteine and trans-sulfurated to cysteine. The GIT accounts for about 25 % of the whole-body transmethylation and trans-sulfuration.

Sulfur- and seleno-containing amino acids [PDF]
Amino Acids, 2011 This special issue is devoted to professor Toshihiko Ubuka (1934–2008), a distinguished Japanese biochemist who, in his scientific life, researched the metabolism and function of cysteine, sulfur nutrition, modification and renaturation of proteins and the possible significance of cysteine metabolites in antioxidation processes in liver cell ...

Sulfur-Containing Amino Acids and Lipid Metabolism [PDF]
The Journal of Nutrition, 2020 The metabolism of methionine and cysteine in the body tissues determines the concentrations of several metabolites with various biologic activities, including homocysteine, hydrogen sulfide (H2S), taurine, and glutathione. Hyperhomocysteinemia, which is correlated with lower HDL cholesterol in blood in volunteers and animal models, has been associated ...

Aqueous Amino Acids and Proteins Near the Surface of Gold in Hydrophilic and Hydrophobic Force Fields [PDF]
, 2014 We calculate potentials of the mean force for twenty amino acids in the vicinity of the (111) surface of gold, for several dipeptides, and for some analogs of the side chains, using molecular dynamics simulations and the umbrella sampling method.

The Sulfur-Containing Amino Acids: An Overview [PDF]
The Journal of Nutrition, 2006 Methionine, cysteine, homocysteine, and taurine are the 4 common sulfur-containing amino acids, but only the first 2 are incorporated into proteins. Sulfur belongs to the same group in the periodic table as oxygen but is much less electronegative. This difference accounts for some of the distinctive properties of the sulfur-containing amino acids ...

, 2020 The chalcogen elements oxygen, sulfur, and selenium are essential constituents of side chain functions of natural amino acids. Conversely, no structural and biological function has been discovered so far for the heavier and more metallic tellurium ...

Remnants of an ancient metabolism without phosphate [PDF]
, 2017 Phosphate is essential for all living systems, serving as a building block of genetic and metabolic machinery. However, it is unclear how phosphate could have assumed these central roles on primordial Earth, given its poor geochemical accessibility.

OENO One, 2022 Thiols are a group of highly potent aroma compounds found in many Vitis vinifera wines. In berries, thiols occur as precursors formed from a thiol attached to an amino moiety (e.g., cysteine and glutathione).
